Abstract

We present millimetre-line imaging of the Galactic H II region Sh 104. We show that it is surrounded by a ring of molecular gas and dust. Four large molecular condensations are regularly spaced around the ring. These condensations are themselves fragmented and contain several massive dense cores. A deeply embedded cluster is observed in the near IR towards the largest condensation. It contains at least one massive star ionizing an ultra-compact H II region. The Sh 104 region is a good illustration of the "collect and collapse" model for star formation triggered by the expansion of an H II region.
